Absolute configurations of the three consecutive chiral centers in the cyclic depsipeptide microtermolide A have been tentatively assigned as 2?R, 3?R, and 4?R. However, on the basis of a structural comparison with vinylamycin, another depsipeptide with a unique 4-amino-2,4-pentadienolate structure, the chiral centers could also be assigned as 2?R, 3?R, and 4?S. Here, the first total synthesis of microtermolide A is reported and the configurations of the three consecutive chiral centers were confirmed to be 2?R, 3?R, and 4?S. A similar approach was used to determine the analogous centers in microtermolide B as 2?R, 3?R, and 4?S.

, p. 789 - 798 (2007/10/02)
The mixed open-chain imide N-(3-chloro-4-hydroxyphenylacetyl)fumarate (1), named coniothyriomycin, was isolated as a metabolite of the fungus Coniothyrium.The natural product 1 and the analoguos imides 13-15 and 22-24 have been synthesized by base-catalyzed condensation of the imidates 12a-f with acid chlorides 6a-c or the mixed anhydride 21.The compounds 1 and 13-15 were shown to posess remarkable fungicidal and herbicidal activities in short-termed tests. Key Words: Fungal metabolites / Imides, open-chain / Fungicidal activity / Coniothriomycin
